# Using Vault Signer

## Summary

* For a selection of cryptocurrencies, you will be able to hold them in custody on Ledger Enterprise and interact with them via an extension.
* This includes **Cosmos** and **Near** with the Ledger Wallet™ (formerly Ledger Live™) application functioning as an external wallet.
* Please note that the account balance for these cryptocurrencies will not be displayed in Ledger Enterprise. Users are advised to rely on the blockchain or Ledger Wallet for balance information.

## How does this feature work?

The Ledger Enterprise platform combines the functionality of both a crafter and signer wallet, allowing users to seamlessly integrate coins and perform crafting and signing transactions in one location.. This integration is costly in resources and time to develop, encouraging us to look for a more efficient, faster solution which would still retain all of the security and trust you can expect from Ledger Enterprise and the Vault platform.

With the **Vault Signer** feature, an external wallet takes on the role of the crafter, while the Ledger Enterprise platform retains all control of the signer. This guarantees that transactions will still have to follow the governance rules enforced by the HSM. The biggest change is that the transactions will be crafted on the extension instead of the Vault.

In a first release, users will be able to connect the workspace to Ledger Wallet(tm) formerly Ledger Live, craft the transaction on the application and approve the request on Ledger Enterprise with their PSD.
